Biology

Rotom transforming

Rotom has a body of plasma and shaped like a lightning rod. There is a whitish blue aura of electricity around it that forms lightning bolt-shaped arms. It has teeth, and its unique, blue eyes have a dividing line across them. As seen in the anime, Rotom will often pull pranks on unsuspecting people.

Rotom and the appliances

Rotom has the ability to enter and control appliances. Starting in Platinum, it also has five extra forms, each based on a household appliance, which can be accessed by possessing specific appliances. The possessed appliances are based on a microwave oven (Heat Rotom), washing machine (Wash Rotom), refrigerator (Frost Rotom), electric fan (Fan Rotom), and a lawnmower (Mow Rotom). Rotom's eyes and electric aura will change colors when it changes form: red for Heat Rotom, blue as Wash Rotom, purple as Frost Rotom, yellow as Fan Rotom, and green as Mow Rotom.

Mow Rotom in Pokémon Pocket Monsters

In Pokémon Adventures, Rotom appeared at the Old Chateau where it caused havoc for Diamond and Pearl until Diamond eventually caught it when it was hiding in the television. The same Rotom made another appearance when Diamond and Pearl returned to the Old Chateau to try to protect it from Charon. Like in its previous appearance, Rotom caused havoc for the boys and ran away to the Galactic Eterna Building where it transformed into its 5 forms and attacked them. Eventually Diamond found out it was just trying to play with them and bonded with it. After telling Rotom of their plan to protect it, Rotom decided to join them.

Trivia

When Rotom is encountered in the Old Chateau in Diamond, Pearl and Platinum, the music is the same as legendary encounters, although it is not usually classified as one. Rotom is, to date, the only non-legendary Pokémon to do this.

With the exception of Unown and Spinda, Rotom has the most forms of any non-legendary Pokémon, with six in total.

Rotom has the most interchangeable forms of any non-legendary Pokémon.

When Rotom transforms, it learns a new move in the same way that other Pokémon may learn new moves upon evolving. The move is replaced by another if Rotom possesses another object, and is deleted when Rotom transforms back to its normal form. If the only move that Rotom knows right before reverting to its original form is exclusive to its alternate form, then that move will be replaced with ThunderShock.

Generation V type change

Rotom is only the third Pokémon to have its types changed, after Magnemite and Magneton: its alternate forms, while sharing the Electric/Ghost type combination with normal Rotom in Generation IV, have their Ghost type exchanged for the type of move they learn from Generation V onward, with Heat Rotom being Electric/Fire, Wash Rotom being Electric/Water, Fan Rotom being Electric/Flying, Frost Rotom being Electric/Ice, and Mow Rotom being Electric/Grass.

No other Pokémon has the same typecombination as Normal, Heat, Frost, and Mow Rotom.

Despite becoming part Flying-type, Fan Rotom retains the Ability Levitate, being the only Flying-type Pokémon with this Ability, which grants it a 'double immunity' to Ground-type moves.

All of Rotom's appliance forms except Mow Rotom are tied for or have the fewest weaknesses of all Pokémon of their secondary types.
